My Oscar was recently diagnosed with diabetes and this came shortly after he had two grand mal seizures. Most of the information available attributes seizures with hypoglycemia, but not hyperglycemia. Has anyone else seen or heard about seizures in cats experiencing hyperglycemia before? It is entirely possible he may have been poisoned after being outside in the rain and potentially walking through old pesticide (from ants this summer) but I'm not sure how likely that could be. I have since rinsed any areas that are covered from the rain but may have pesticide residue. I'll also prevent him from going to these areas, just in case. Both seizures occurred within 12 hours of each other, but no seizures since. These seizures occurred before the diabetes diagnosis. Thanks in advance!
